//@ check-pass

// this test checks that the `dead_code` lint is *NOT* being emitted
// for `foo` as `foo` is being used by `main`, and so the `#[expect]`
// is unfulfilled
//
// it also checks that the `dead_code` lint is also *NOT* emitted
// for `bar` as it's suppresed by the `#[expect]` on `bar`
